Advanced Materials

At a small farm in the green highlands of southern Ethiopia, a man swings a blade into a plant that looks exactly like a banana tree — but will never grow a single banana you can eat. His family has scraped its trunk for food for generations and tossed the stringy leftovers aside. Now laboratories on three continents are soaking those same strings in resin, loading them into testing machines — and they're holding. Holding about as well as the material inside your boat hull, your car's body panels, and the giant spinning blades of almost every wind turbine on Earth.

That material is fiberglass — born from a lab accident in the 1930s, heavy for what it does, and nearly impossible to recycle. This is the story of how a plant from the African highlands and a handful of its cousins became the quietest threat fiberglass has ever faced: why plant fibers match glass pound-for-pound, the water problem that kept them on the sidelines for years, the chemistry and the single change in thinking that finally cracked it, the jute boat that crossed an ocean, the European shipyards already taking orders — and the one wall left between a plant fiber in a lab and a plant fiber in the hull of a ferry: trust.

About HDC Concrete, video is too long all pertinent information could probably be covered in two minutes.
